        <p>People on Mars count their numbers with base 13:</p>
<ul>
<li>Zero on Earth is called “tret” on Mars.</li>
<li>The numbers 1 to 12 on Earch is called “jan, feb, mar, apr, may, jun, jly, aug, sep, oct, nov, dec” on Mars, respectively.</li>
<li>For the next higher digit, Mars people name the 12 numbers as “tam, hel, maa, huh, tou, kes, hei, elo, syy, lok, mer, jou”, respectively.<br>For examples, the number 29 on Earth is called “hel mar” on Mars; and “elo nov” on Mars corresponds to 115 on Earth. In order to help communication between people from these two planets, you are supposed to write a program for mutual translation between Earth and Mars number systems.</li>
</ul>
<p>Input Specification:</p>
<p>Each input file contains one test case. For each case, the first line contains a positive integer N (&lt; 100). Then N lines follow, each contains a number in [0, 169), given either in the form of an Earth number, or that of Mars.</p>
<p>Output Specification:</p>
<p>For each number, print in a line the corresponding number in the other language.</p>
<p>Sample Input:<br>4<br>29<br>5<br>elo nov<br>tam<br>Sample Output:<br>hel mar<br>may<br>115<br>13</p>
<p>火星人是以13进制计数的：</p>
<ul>
<li>地球人的0被火星人称为tret。</li>
<li>地球人数字1到12的火星文分别为：jan, feb, mar, apr, may, jun, jly, aug, sep, oct, nov, dec。</li>
<li>火星人将进位以后的12个高位数字分别称为：tam, hel, maa, huh, tou, kes, hei, elo, syy, lok, mer, jou。<br>例如地球人的数字“29”翻译成火星文就是“hel mar”；而火星文“elo nov”对应地球数字“115”。为了方便交流，请你编写程序实现地球和火星数字之间的互译。</li>
</ul>
<p>输入格式：</p>
<p>输入第一行给出一个正整数N（&lt;100），随后N行，每行给出一个[0, 169)区间内的数字 —— 或者是地球文，或者是火星文。</p>
<p>输出格式：</p>
<p>对应输入的每一行，在一行中输出翻译后的另一种语言的数字。</p>
<p>输入样例：<br>4<br>29<br>5<br>elo nov<br>tam<br>输出样例：<br>hel mar<br>may<br>115<br>13</p>

<p>%<em>c其中%c是读一个字符，而中间的</em>号是跳过一个字符。意思就是读取一个字符但并不赋值给变量。<br>如果不添加这个，也可以在scanf后面加一个getchar吸收换行符。<br>另外这里使用getline是因为字符串有些是有空格分割的，如果用printf(“%s”, str)和cin &gt;&gt; str;都会断开</p>
